Overview
CVE-2025-13199 describes a path traversal vulnerability discovered in Email Logging Interface 2.0. This vulnerability allows a local attacker to read arbitrary files on the system by manipulating the ‘Username’ argument within the signup.cpp file. The public availability of an exploit increases the risk associated with this vulnerability.
Technical Details
The vulnerability resides in the signup.cpp file of Email Logging Interface 2.0. Specifically, the Username argument is not properly sanitized, allowing an attacker with local access to inject path traversal sequences like ../filedir. This manipulation allows the attacker to bypass intended directory restrictions and access files outside of the expected location.
An attacker can exploit this vulnerability by crafting a malicious input containing the path traversal sequence when creating a new user account. The lack of proper input validation allows the application to interpret the sequence, leading to unauthorized file access.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-13199 a score of 5.3 (Medium).
- Attack Vector: Local (L)
- Attack Complexity: Low (L)
- Privileges Required: None (N)
- User Interaction: None (N)
- Scope: Unchanged (U)
- Confidentiality Impact: Low (L)
- Integrity Impact: None (N)
- Availability Impact: None (N)
The medium severity is attributed to the local attack vector and the confidentiality impact. While an attacker needs local access, the ease of exploitation contributes to the overall risk.
Possible Impact
Successful exploitation of CVE-2025-13199 could allow a local attacker to:
- Read sensitive configuration files.
- Access user data stored on the system.
- Potentially escalate privileges by accessing files that contain credentials.
The impact is primarily related to information disclosure, potentially leading to further exploitation depending on the contents of the accessed files.
Mitigation or Patch Steps
To mitigate this vulnerability, the following steps are recommended:
- Input Validation: Implement robust input validation on the
Usernameargument in thesignup.cppfile. Specifically, filter out or sanitize any path traversal sequences (e.g.,../,..\). - Least Privilege Principle: Ensure the application runs with the minimum necessary privileges to reduce the potential impact of a successful exploit.
- Patching: Check Code-Projects.org for any available patches or updates for Email Logging Interface 2.0. Apply the patch as soon as possible.
- Regular Security Audits: Conduct regular security audits of the application’s code to identify and address potential vulnerabilities.
